BACKGROUND A major challenge for antiviral treatment of hepatitis C virus (HCV) infection is viral resistance, potentially resulting from the high variability of HCV envelope glycoproteins and subsequent selection of strains with enhanced infectivity and/or immune escape. METHODS We used a bioinformatics and functional approach to investigate whether E1/E2 envelope glycoprotein structure and ...
objective(s): the ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. the aim of this study was to evaluate the uptake of 18ffluorothymidine (flt) pet in renal cell carcinoma (rcc), and to compare this to 18f-fluorodeoxyglucose (fdg), and to an immunohistochemical measure of cellular proliferatio...

objective(s): the aim of this study was to analyze detection rates and effectiveness of 18f-fluorodeoxyglucose positron emission tomography (fdg-pet) cancer screening program for prostate cancer in japan, which is defined as a cancer-screening program for subjects without known cancer. it contains fdg-pet aimed at detection of cancer at an early stage with or without additional screening tests ...
background: to retrospectively describe imaging characteristics of liver metastases on fused fdg-pet/ mri data sets and to compare the diagnostic accuracy of mri and fused fdg-pet/mri data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. materials and methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by fdg-pet/ct and l...
pp/pep blends, because of different solubility factors, are incompatible. the aim of this research was to use pp-g-ma compatibilizer in a two-component blend. after preparing this compatibilizer in internal mixer and investigating different parameters on producing process, optimum compatibilization was obtained. pp/pet (60/40) blend fibers with different percentages of this compatibilizer in tw...
This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients a...
با توجه به اینکه بطری¬های آب تولید شده از پلی¬اتیلن-ترفتالات یا pet سریعترین رشد را در صنعت نوشیدنی دارند، بازیافت ضایعات پلاستیکی در سراسر جهان به یک چالش بزرگ تبدیل شده است. در مطالعه حاضر روشی برای استفاده مجدد از ضایعات پلاستیکی جهت اصلاح و بهبود خصوصیات خاک ارائه شده است. آزمایش سه¬محوری تحکیم-یافته زهکشی¬شده به منظور تعیین خصوصیات تنش-کرنش و اتساع خاک ماسه¬ای مسلح¬شده با pet به ازای تنش ه...
in this paper, we review novel techniques in the emerging field of spatiotemporal 4d pet imaging. we will discuss existing limitations in conventional dynamic pet imaging which involves independent reconstruction of dynamic pet datasets. various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that utilize iterative temporal smooth...
